Constructor Detail

Code

public Code(HMethod parent,
            Instr instrs,
            Derivation deriv,
            Frame frame)

Creates a Code.

Method Detail

getDerivation

public Derivation getDerivation()

Description copied from class: Code

Returns the Derivation associated with this. Returns null if Derivation information is not available.

Overrides:

getDerivation in class Code

getName

public String getName()

Description copied from class: HCode

Return the name of this code view. The default bytecode view is named "bytecode". It is suggested that additional views be named in a similarly human-friendly fashion.

Specified by:

getName in class HCode<Instr>

getRegisterName

public String getRegisterName(Instr i,
                              Temp val,
                              String suffix)

Description copied from class: Code

Returns an assembly code identifier for the register that val will be stored into.

Specified by:

getRegisterName in class Code

assignRegister

public void assignRegister(Instr i,
                           Temp pr,
                           List regs)

registerAssigned

public boolean registerAssigned(Instr i,
                                Temp pr)
